Warm and comfortable. Coleman considered many aspects in the design of this bag.
The zipper is designed to not bind with the fabric – it has comfortable fabric around
the head and neck – it feels sturdy, warm and comfortable – and don't miss the hidden
velcro pouch just inside the upper opening where you can store keys, wallet, cell hone,
or other important property.
Because this is made with synthetic material, it probably weighs more and may not pack
down to as small as a down bag would, but it still feels light and compresses to a reasonable
size. See the attached photo of the bag repacked using the 'stuffing' method. Note that I
was not able to zip up the packing zipper on the storage bag and I don't know if the bag
will compress enough to allow that after it has been unpacked. It seems that the zipper
may be for shelf presentation and not intended for repacking, in my novice opinion.

I've only used this once since purchasing but am pleased with the product. Here's a quick rundown of my thoughts:
Pros:
– Definitely keeps you warm***
– Very soft. It's seriously comfortable.
– The zipper really doesn't get snagged. Again, I've only used it once since purchasing but I kept zipping and unzipping the bag every day/night and it just would not get snagged!
Cons:
– ***The bag was almost too warm. I used it in 60-65º nights and I was pretty much right on the border between too warm and comfortable. I personally cannot sleep if my body is too warm and this sleeping bag was pushing it. I woke up a few times in the middle of the night, each night, and had to unzip the bag a little to let some cold air get in, so I could get comfortable and fall back asleep.
Issues (To clarify: these are NOT cons of the products. Cons are when the product has some sort of manufacture/physical/etc. issue ITSELF. These are MY personal issues I had with the bag):
– I move a lot when I sleep. And I mean a lot. It takes a while for me to find a position where my mind will finally tell me, "okay you're good, let's sleep". This was a problem for me when I had this bag zipped up. I was fighting with the bag every night. If you move a lot, I highly recommend you either buy two of these and zip them together, or just use this to lay on and get another blanket to use on top. OR just don't get it at all and get something bigger.
– The material is soft but your skin can get caught on it. My hands and feet are kind of rough. The skin around my nails are constantly peeling and the bottoms of my feet aren't the smoothest. Both areas were constantly getting "snagged" on the material. It's more annoying than anything but it takes away from the comfort. Honestly, that can happen with anything of similar material though. I just thought it was worth mentioning.
Overall, I have to give it 4 out of 5 stars. It is a nice bag and I would definitely recommend it.

It is and does what it is supposed to be and do.
I like how the SACK has two size settings, so to speak: One for when you don't want to bother rolling the sleeping bag up extra tightly and one for when you do. You can actually make it pretty small, and we take it backpacking, though it's probably too big for people who are more hardcore about backpacking and weight.
The little HOOKS on the sides do aid you in folding it up (though, if you're skilled enough, you don't need to use them).
The STRINGS for tying it before stuffing it into the sack are (as with all sleeping bags that are going to go into a bag/case anyway), useless, and using them actually makes it harder to load the sleeping bag into its bag/case.
The ZIPPER works fine and we have had no trouble with it, even with extensive use (every time we use it, we fully unzip it to use it as a blanket on top of another fully unzipped sleeping bag "mattress", and we are also easily able to zip it onto another sleeping bag when we want to).
If it suits your needs in terms of temperature, go for it!
Addendums:
1. Reading the other reviews complaining about the fabric inside… I agree, it's slightly uncomfortable (catches on rough fingernails, etc.). I'd take away a half star, if I could, but not a whole star.
2. I don't have trouble making it fit into the sack, even using the "smaller setting" (i.e., with the zipper on the sack zipped up.) I'm not trying to be mean but, really, I think the people complaining about that just aren't that good at rolling up sleeping bags. It's not easy to get it in the tighter way but it's VERY easy to get it in the regular way, and wholly possible to get it in the tighter way, too. I do it every single time, and often without assistance (though having two people involved makes it easier). An important hint: If you want to get it into the sack and have the sack zipped, too (making it smaller), it needs to be zipped BEFORE you put the sleeping bag in. (You will not be able to zip it afterwards!) So the tricky part is holding the zipper up so that it doesn't unzip itself as you stuff the sleeping bag in. Just roll it up tight and keep it tight while you pull the sack around it. It works best if one person's duty is just to keep the sleeping bag condensed and hold the zipper of the sack in place while the other person pulls the sack around the sleeping bag. It CAN be done! 🙂

Love it! It is warm, soft and roomy. I am 5'9. The only issue is that it is pretty tough to roll up and stuff into the pouch in came in. The pouch has an expansion zipper. Without it fully open, you wouldn't be able to pack it up.

Present for my daughter friend, nice and comfortable.
